Hi, Before I dive in too deeply to vdsm-hook-qemucmdline I'd like to know if it is the correct solution to my needs. I want to add the following (type of) parameters to VM startup -object memory-backend-file,id=mem1,share=on,mem-path=/dev/dax0.0,size=$PMEM_SIZE,align=2M \-device nvdimm,id=nvdimm1,memdev=mem1,label-size=128k \ Is the vdsm-hook-qemucmdline the correct tool? Can I use (add the params) it also from the ansible playbook (via ovirt roles) somehow? Thanks, Sakari
